SPECIFICATION forming part of Letters Patent No. 524,886, dated August21, 1894.

Application filed June '1, 1894. Serial No. 513,786. (No model.)

To @ZZ w/tom t may concern:

Be it known that I, ALFRED A. COLLINS, of Danville, in the county ofRockingham and State of New Hampshire, have invented a new and usefulImprovement in Boots or Shoes, which will, in connection with the accompanying drawings, be hereinafter fully described, and specificallydefined in the appended claim.

My invention relates to an improvement 1n boots or shoes of 'the varietyknown 4as spring-heel shoes in which the sole extends the entire lengthof the shoe in one piece, under both heel and toe, and also is bent up-Ward to form the breast of the heel and the arch of the shank. And theinvention conslsts in the peculiar construction of the shank portion ofthe sole by which the edges thereof are notched and thinned by cuttingor compressing, and in the adaptation of the heel lifts thereto byrecurving the front edges thereof as hereinafter fully described, sothat the completed shoe is increased in strength and firmness in thearchAof the shank and rendered much more durable at the bend of the solealong the lower edge of the breast of the heel, where such shoes areusually weakened by the customary channel cut across .the sole at auniform depth.

In the drawings: Figure 1. is an edge elevation of a sole notched andthinned at the edges in accordance with my invention. Fig. 2. is avertical section taken longitudinally through the center of Fig. 3, andas on line y, y. Fig. 3. is aplan or top view of the sole shown in Fig.l. Fig. 4. is a similar view of the same with the addition of a heellift thereon. Fig. 5. is a vertical section taken longitudinally throughthe center of Fig. 3.

Fig. 6. is an elevation of the sole and heelV lifts thereon the solebeing bent into shape as when forming a part of a completed shoe.

, Fig. 7. is a transverse section taken as on line 10. is a perspectiveview of the heel showing the sole in section at the upper turn of thesame in the shank.

The sole A is notched and thinned, by cntting or compression, on itsedges near the heel portion thereof as shown at a Fig. l, which notchesor depressions a are formed deeply at the extreme edges, but diminishindepth and gradually fade out toward the center, leaving the middleportion b at fullthickresponding outer portions of the heel lifts at e,e, thus conforming to the transverse configuration of the adjacent faceof the sole, and securing a firm bearing of the same against the breastofthe lifts from one side to the other as clearly shown in Fig. 10, andwithout distorting the sole from its proper shape or weakening it by theusual crosschannel cut at uniform depth therein under the breast of theheel.

The sole thus constructed with edge depressions or notches and fullcentral thickness, in conjunction with recurved lifts into which thesole is upturned as described and shown in Fig. 10, constitutes theessential feature of my invention. When the sole is thus bent intoposition relatively to the heel lifts, and into conformity with thebottom of the last, and is secured to the upper in the usual manner,ashoe is produced of unusual firmness in the arch A of the shank, and ofa more substantial and durable heel tread, and one more capable ofmaintaining its good form under the tread of the wearer.

The convexity of the bottomV of the last on which the shoe is made bendsthe sole so that the bottom thereof is correspondingly convex in theshank A as shown in Fig. 9 and the having their front edges d recurvedto com ro forward edge of liftC as shown in Fig. 7 Vis lform tothetransverse congnration of the slightly depressed thereby. face of theupturned sole `which bears against claimm them; substantially as and forthe purposes 5 1n a. shoe of the described spring-heel vaspeeied.

riety, the combination of a sole formed with ALFRED A. COLLINS. notchedor thinned edges, as at a,a,ra.nd full Witnesses: center, as at b; witha heel lift, or lifts, in- CLARENCE M. COLLINS,

terposed between the sole and upper, and WALTER A. KIMBELL.
